How to Save SHSH Blobs for iOS 4.1 to Get iOS 4.2 Jailbreak Untethered

It is highly recommended that you save the iOS 4.1 SHSH Blobs before the public release of iOS 4.2 to get the untethered jailbreak for iOS 4.2. Apple has already rolled out the iOS 4.2 GM version and the final version is coming within few days after which Apple will not sign the old firmware.

According to a tweet by Comex, all users who have iOS 4.1 SHSH blobs saved will get untethered iOS 4.2 jailbreak and the others might be shifted to tethered iOS 4.2 jailbreak.

Moreover, if you have updated your idevice to iOS 4.2 GM, you can downgrade to iOS 4.1 anytime provided iOS 4.1 SHSH Blobs are already saved.

Though Cydia automatically stores the SHSH Blobs of every jailbreaked idevice, but it is better to save them manually and locally with the help of TinyUmbrella.

Step 1: Download the latest TinyUmbrella.

Step 2: Run the TinyUmbrella and attach your iPhone with the PC. Make it sure that iTunes is not running.

Step 3: TinyUmbrella will automatically detect your iPhone.

Step 4: Now press the “Save SHSH” button. Depending on the load, Cydia server might take some time to process your request. Once completed you will see the saved SHSH blobs on the screen of Cydia App.
